angularjs - Set angular scope variable in markup

Question

Simple question: How can I set a scope value in html, to be read by my controller?

var app = angular.module('app', []);

app.controller('MyController', function($scope) {
  console.log($scope.myVar);
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app='app'>
  <div ng-controller="MyController" app-myVar="test">
    {{myVar}}
  </div>
</div>

ng-init does not work when you are assigning variables inside loop. Use {{myVariable=whatever;""}}

The trailing "" stops the Angular expression being evaluated to any text.

Then you can simply call {{myVariable}} to output your variable value.

I found this very useful when iterating multiple nested arrays and I wanted to keep my current iteration info in one variable instead of querying it multiple times.
